Can someone help me explain this ph reading?

Post by skehole »

Attached are 2 pictures. One from the u-app and the other from reeftronics. Can someone explain why I'm getting the low ph spikes on the reeftronics graph?

Do you have an ATO dumping fresh water in at those periods.
The fresh RODI water can be throwing off your probe if the place that the water gets put into the sump is to close to the probe,

Top off water is added after the probe location. Good idea though!

Try taking the probe out of the tank and putting it in a glass or cup of tank water and see if it still have those drops.

I'm mainly curious why it would show on one app but not the other? I will try the cup though...

The RA graphs do not show 0 values. I know those aren't 0, but I have a feeling that reeftronics may be doing some averaging there for the graphing... that's my guess. RA would just throw out those values.
